BACKGROUND
The aim of this study was to observe the concentrations of trace metals boron, lithium, rubidium, antimony, tin and strontium in the serum of athletes from different modalities and sedentary subjects and the possible influence that different energy sports training modalities can have on their concentration.
METHODS
Eighty professional athletes and 31 sedentary males participated in the present survey. All of them were living in Cáceres (Spain). Serum boron, lithium, rubidium, antimony, tin and strontium analysis was performed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
RESULTS
The results show higher concentrations in athletes on tin ( < 0.01), rubidium and antimony ( < 0.001) than the control group. In the case of tin, this item had the highest concentrations only in aerobic sports modalities. Regarding rubidium and antimony, the highest concentrations are found in athletes with lower oxygen consumption (aerobic-anaerobic) ( < 0.001), followed by anaerobic group ( < 0.001).
CONCLUSION
Our research shows that, probably due to increased water and air intake, especially, trace elements rubidium, antimony and tin reveal major differences in serum concentration of athletes in relation to sedentary subjects. On the other hand, physical training does not change the serum concentration of Boron, Lithium and strontium.
背景
本研究的目的是观察不同运动方式的运动员和久坐不动者血清中硼、锂、铷、锑、锡和锶等微量元素的浓度，以及不同能量运动训练方式对其浓度可能产生的影响。
方法
80名职业运动员和31名久坐不动的男性参与了本次调查。他们都生活在西班牙的卡塞雷斯。采用电感耦合等离子体质谱法（ICP-MS）对血清中的硼、锂、铷、锑、锡和锶进行分析。
结果
结果显示，运动员血清中锡（<0.01）、铷和锑（<0.001）的浓度高于对照组。就锡而言，仅在有氧运动项目中该元素浓度最高。关于铷和锑，在耗氧量较低的运动员（有氧-无氧运动）中浓度最高（<0.001），其次是无氧运动组（<0.001）。
结论
我们的研究表明，可能由于水和空气摄入量增加，特别是微量元素铷、锑和锡，运动员血清浓度与久坐不动者相比存在显著差异。另一方面，体育锻炼不会改变硼、锂和锶的血清浓度。
